Sugarcane ethanol production occurs in non-sterile conditions, and microbial contamination can decrease productivity. In this study, we assessed the microbial diversity of contaminants of ethanol production in an industrial facility in Brazil. Samples obtained at different stages were analyzed by pyrosequencing-based profiling of bacterial and archaeal 16S rRNA genes and the fungal internal transcribed spacer region. A total of 355 bacterial groups, 22 archaeal groups, and 203 fungal groups were identified, and community changes were related to temperature changes at certain stages. After fermentation, Lactobacillus and unclassified Lactobacillaceae accounted for nearly 100 % of the bacterial sequences. Predominant Fungi groups were ?unclassified Fungi,?Meyerozyma, and Candida. The predominant Archaea group was unclassified Thaumarchaeota. This is the first work to assess the diversity of Bacteria, and Archaea and Fungi associated with the industrial process of sugarcane-ethanol production using culture-independent techniques. |

The family Hormogastridae, consists of various genera and species of large and middle-sized
earthworms distributed in western Palearctic Region, almost exclusive to the countries and
islands of the western Mediterranean. In central Iberian Peninsula only one described species
within Hormogaster genus is found, Hormogaster elisae, an endemic species to this area. This
species can be very abundant in sandy and poor in organic matter soils, with strong erosion and
summer aridity. Climate change will presumably favour the extension of this kind of soils, where
Hormogaster genera and specifically H. elisae could be the only ones capable of thriving. Because
of that, their ecological importance could become crucial and hence, it is necessary to look into
their genetic variability in order to develop conservation and management programmes.
The objectives of this study were to determine the levels of genetic differentiation and estimate
the amount of gene flow occurring among populations of H. elisae as well as to study the possible
phylogenetic relationships among them. For this purpose, first subunit of cytochrome c oxidase
mitochondrial gene (COI) was sequenced for 82 individuals from 7 localities, resulting in 38
haplotypes exclusive to localities.
The analysis of molecular variance indicated a significant interpopulation genetic diversity and
the Mantel test revealed a pattern of isolation by distance. Values of genetic divergence were
surprisingly high (up to 20.20%) and the haplotype network (constructed using statistical
parsimony) showed a clear separation among populations. Phylogenetic analyses (Neighborjoining,
Maximum parsimony, Maximum-likelihood and Bayesian) also showed an agreement
between the generated clades and the geographic location, supported by high bootstrap and
posterior probability values.
The results suggest the occurrence of more than one Hormogaster species in central Iberian
Peninsula. Therefore, we are currently studying the problem in a wider spatial scale and with
different approaches to take a final decision about the limit of those species MenosThe family Hormogastridae, consists of various genera and species of large and middle-sized
